    How youll clean it (keep in mind everything you learned from your coursework and our EDA discussion in class 3.
Implementation methodology and strategies: How will you go about to implement your proposal? Is it an interactive dashboard, a predictive model or both? Describe the methods and strategies that should be used in order to create and implement the interactive dashboard and/or predictive model. Be detailed about statistical tests, graphs, and/or model packages that can be used and how. Create mock-ups of screen shots or use some similar ones you found on your literature review (enough for the reader to understand how it can be created and implemented)
